ORE-SAMPLING APPARATUS.

To all whom it may concern:

Be it known that I, ALEXANDER J. Mc- CoNn, a citizen of the UnitedStates, residing at Reno, in the county of Tashoe and State of Nevada,have invented certain new and useful Improvements in Ore-SamplingApparatus, of which the following is a specilication.

My invention relates to the class of oresampling devices. Its object isto provide a simple and effective means for taking a fair,representative sample from the ore while being transferred from theCrusher to the mill, or storage bins, or cars, as the case may be,Without interfering with such transfer, and without Waste of time,labor' or material.

My invention consists, primarily, in a traveling carrier having asuccession of pans separated by open intervals bearing a given lesserproportion to said pans, whereby the ore which is supplied in acontinuous stream to the passing succession of pans and open intervals,is divided into two portions, the lesser, which passes through theintervals, being taken as the sample.

My invention further consists in means for successively extractinglesser proportions of the iirst extraction, and for crushing theseproportions to successively increasing neness, all in a continuousoperation, until the sample finally taken is fair and represent-ative.

Referring to the accompanying drawings Figure 1 is a side view of myoresampling apparatus. Fig. 2 is an end view of the same.

1 is a frame, in which is mounted, upon sprockets 2, an endlesstraveling pan-corrveyer, comprising side chains 3 and pans l. These pansmay be of any suitable form, as, for example, that here shown, eachconsisting of separate sections overlapping on their sides, the endsections being terminally flanged, thus forming one long pan adapted toturn about the sprockets. There may be any number of these pans, andthey may have any given length. The pans are separated by givenintervals indicated by 5, which intervals must be of a length bearing astated proportion to the length of the pans, say, for example,one-fourth. At these intervals the conveyer is open. Abo ve theconveyer, near its head, is a crushing device 6 of any suitablecharacter, which is adapted to crush the ore to any given initialSpecification of Letters Patent.

fineness, say, for example, to reduce it an inch and a half mesh orring. The crusher G discharges the orc into a chute 7, which lies abovethe conveye and which delivers said crushed ore in a continuous streamto the pans l and to the open intervals 5 ot' the conveyer as they passunder it.

Directly under the ripper' course of the conveyer and in line with thedelivery end of the chute 7 is the open mouth of a hopper' 8, whichinclines outwardly and is adapted to deliver to an elevator t), which inturn delivers to a feed-hopper l() above. Under the feed-hopper 10 is asecond crushing-device 11, of suitable character adjusted to crush theore to a greater ineness than that resulting from the operation of theFirstcrusher, say, for example, the crusher 11 reduces the ore to athree-quarter inch mesh or ring. 'The crusher 11 discharges into a chute12 which delivers to the passing succession of pans and open intervalsof the conveyor. Under the conveyer, in line with said chute 12 is ahopper 13, which delivers to a second elevator 14. Ihis elevatordelivers to a feed-hopper 15 of a third crushing-device 16, which isadjusted to reduce the or'e to a still greater' lineness, say, forexample, to a quarter inch mesh or ring. The Crusher 16 delivers to achute 1T which delivers to the conveyer, as before, and to a hopper 1Sunder said conveyor. This may terminate the series, as illustrated;though it is evident, that said series may be extended at either end, asmay be desired.

I need not describe in detail the various power-transmitting devices tooperate the conveyer, the Crushers and the elevators, as these form nopart of my invention and are su'fliciently indicated in the drawings.

The operation of the apparatus is as follows :-The ore is supplied inany way, as by hand or from a chute, to the first crushcr 6, by which itis reduced to a given initial fineness, as before stated. In thiscondition it is continuously delivered from the chute 7. In theproportion above stated, between the pans 4 and the open intervals 5,four'- iifths of the ore will fall into each passing pan, and one-fifth,which is taken for the sample, will fall through each open interval 5. This sample portion falls into the hopper 8, and is carried up by theelevator 9 and delivered through the feed-hoppcr 10 to the secondCrusher 1l. In this Crusher it is reduced to a greater fineness, asbefore stated,

and, thus reduced in iineness, it is delivered, four-fifths to thepassing pans 4 and onefifth to the open intervals 5. This one-fifthsample is, of course, now one twenty-ifth of the whole, and saiddiminished sample is delivered by the hopper 13 to the second elevator14, which, through the feed-hopper 15, delivers it to the third crusher16. In this crusher it is reduced to still greater fineness, as stated,and from the crusher it is delivered, four-fifths to the pans 4 andonefifth to the open intervals 5; and this onefifth sample is now, 0fcourse, one one-hundred and twenty-fifth of the whole. This sample istaken from the final hopper for assay Qurposes to determine the value ofthe ore. n account of its successive extractions and because of itssuccessive reductions in the Crushers it is a fair, representativesample. In practice, with the proportions above given and the successiveselections as stated, it is 16 pounds to the ton, which if we multiplyby ten represents 160 pounds to 10 tons which is a good working sample.The main body of the ore is, of course, delivered by the pan conveyer tostorage bins or to the mill or the cars, as the case may be. Thesampling is continuous and not wasteful, nor does it involve eXtralabor, for the rejected four-fifths of the successive eX- tractions arereturned to and commingled with the main body of the ore.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is y 1. In an ore-sampling apparatus, thecombination with a traveling carrier having a succession of containersseparated by intervals bearing a given lesser' proportion to saidcontainers, means for supplying ore continuously to said carrier, andmeans for receiving the ore which passes through one of the intervals inthe carrier and again feeding said ore to the traveling carrier.

2. In an ore-sampling apparatus, the combination of a traveling carrierhaving a succession of pans separated by intervals bear'- ing a givenlesser' proportion to said pans; a succession of independent feeders tosupply ore to the passing succession of pans and separating intervals atsuccessive stations along the length of the carrier; means for receivingthe portion of ore supplied by each feeder to the separating intervals;and means for transferring said portion from one receiving means to thesucceeding feeder.

3. In an ore-sampling apparatus, the combination of a traveling carrierhaving a succession of pans separated by intervals bearing a givenlesser proportion to said pans, said intervals being open through thecarrier; a succession of independent feeders to supply the ore incontinuous streams to the passing succession of pans and open intervalsat successive stations along the length of the carrier; a succession ofunderlying receptacles to receive the portion of ore supplied by eachfeeder to the open intervals; and means for transferring said portionfrom one receptacle to the succeeding feeder.

4.
